World's biggest cruise ship will launch on March 31: Specification

The world's biggest and most expensive ever cruise ship is just days away from setting sail on its maiden voyage. Royal Caribbean's 'Symphony of the Seas' is currently docked in in Malaga, Spain where it dwarfs nearby apartment blocks. The ship weighs 228,000 tonnes, and at 1,188 feet long, it is just 20 metres shy of the length of the Empire State Building in New York.

Passersby marvel at the size of the Symphony of the Seas - the world's biggest and most expensive cruise ship. The cruise ship also has a one-of-a-kind ultimate family suite, set over two levels and 1,346 square feet.

The fun-focused suite has a slide installed for guests wanting to get from the upper to the lower level, and also features a floor-to-ceiling Lego wall as well as an air hockey table and a ping pong table. For those wanting to relax, guests in the suite can chill out in the private cinema that comes with a 85-inch HD TV along with a library of video games.
